Cataract surgery or lens exchange? An honest assessment

It is important to distinguish between two terms that are often confused. At EyeLaser Zurich, we advise you transparently on the indication:

1. Cataract surgery

This is a medically necessary procedure.

  • Cause: The natural lens has become cloudy. Vision declines despite glasses.
  • When do we operate? Only when you have subjective symptoms that affect you in everyday life (glare, hazy vision). We do not operate “as a precaution”. It remains a surgical procedure that should be carefully considered—even though it is extremely safe today.

2. Refractive lens exchange (RLE / RLA)

This is a lifestyle procedure to correct refractive errors.

  • Cause: The lens is still clear, but you have age-related long-sightedness (presbyopia) and no longer want to wear varifocal glasses.
  • Standard: Because a healthy organ is being operated on here, our standards for precision, safety and optical outcome are even higher than for classic cataract surgery.

High-tech for your eyes – four levels of precision

We do not settle for the standard. To achieve the best possible results in Zurich, we rely on a combination of four high-end technologies:

1. FLACS: The femtosecond laser replaces the scalpel

In standard surgery, the surgeon opens the eye manually. We optionally offer you Femtosecond Laser-Assisted Cataract Surgery (FLACS).

  • The advantage: The laser creates a perfectly circular incision that is precisely centred. It pre-fragments the cloudy lens so that we need less ultrasound energy. This protects the cornea and speeds up healing.

2. Digital navigation system (markerless alignment)

A premium made-to-measure suit only fits if it sits perfectly. The same applies to toric lenses (for astigmatism).

  • The advantage: Instead of working with imprecise felt-tip markings on the eye, we digitally project the axis of your astigmatism directly into the microscope like a head-up display. This guarantees rotationally stable accuracy of fit.

3. AI biometry (artificial intelligence)

Technology is good; data is better. To calculate your intraocular lens, we use AI algorithms (e.g. Hill-RBF).

  • The advantage: AI recognises patterns in your eye anatomy that conventional formulas miss. We can virtually know even before surgery how you will see afterwards.

4. Brand quality without compromise

Your eye is no place for cost-cutting.

  • The advantage: We implant only lenses from global market leaders (e.g. Zeiss, Alcon, Johnson & Johnson) that have proven themselves millions of times, remain clear long-term (“glistening-free”), and feature UV filters to protect your retina.

To new vision—fear-free and efficient

We have optimised our process to perfectly match the Zurich lifestyle—efficient, safe and comfortable.

Gentle “no-needle” anaesthesia & twilight sedation

Are you afraid of an injection into the eye? You do not need to be.

  • Drop anaesthesia: We numb the eye exclusively with drops. No injection, no pain.
  • Twilight sedation: If desired, our anaesthetist will put you into a light sleep. You breathe independently, do not notice the procedure, and wake up relaxed.

ISBCS: Both eyes in one day

Why live with uneven vision for weeks? Traditionally, eyes are operated on weeks apart.

  • Our offer: If medically suitable, we operate on both eyes on the same day (Immediate Sequential Bilateral Cataract Surgery).
  • Safety: We treat each eye as a completely separate procedure (changing all instruments and the team) to guarantee sterility.
  • Your benefit: Only one appointment, one healing phase, and immediate depth perception.
